IMPACT OF DIALYSIS DURATION AND DIURESIS ON BLADDER CAPACITY AND COMPLIANCE IN END STAGE RENAL DISEASE PATIENTS AWAITING RENAL TRANSPLANT

Sponsor

Sindh Institute of Urology and Transplantation

Enrollment

87 participants

Start Date

Feb 2, 2026

Study Type

OBSERVATIONAL

Conditions

Bladder Dysfunction End-Stage Renal Disease Requiring Haemodialysis

Summary

Patients with end-stage renal disease (ESRD) who are on dialysis for a long time may experience bladder problems as their urine output decreases and normal bladder filling is lacking. As a result, bladder capacity may be reduced and compliance may deteriorate, which can impact the success of kidney transplantation. Our prospective observational study is designed to investigate how dialysis duration and residual urine output (diuresis) influence bladder capacity and compliance in ESRD patients who are waiting for kidney transplantation. The adult patients undergoing regular dialysis will be assessed clinically, and they will also be subjected to laboratory tests, imaging, and urodynamic studies. Through this study, we aim to determine the frequency of bladder malfunction and its correlation with the length of dialysis and the amount of urine excretion. The results might enhance the pre-transplant workup and offer a basis for urological post-transplantation management that could minimize complications.

Interventions

DIAGNOSTIC_TESTObservational Assessment

This is a prospective observational study with no therapeutic or preventive intervention. Participants undergo clinical assessment, including evaluation of dialysis duration and residual urine output, along with laboratory investigations, imaging, and urodynamic studies to assess bladder capacity and compliance.
